feat: geometric graph topology + module pages + phantom link cleanup

Graph topology (Metatron's Cube pattern — 1 center + 12 outer nodes):
- index: now links to ALL 12 other nodes (complete hub)
- Inner ring cycle: hot→log→overview→dashboard→concepts/_index→entities/_index
  - Added: hot↔WikiMap, log↔sources/_index, dashboard↔concepts/_index
  - Added: entities/_index↔hot, entities/_index↔LLM Wiki Pattern
  - Added: sources/_index↔log, sources/_index↔entities/_index
- Outer ring: concepts connected in triangle + Karpathy/sources cross-linked
  - Added: dashboard↔Compounding, entities/_index↔LLM Wiki Pattern

graph.json physics for geometric arrangement:
- repelStrength: 80 (strong push-apart for uniform spacing)
- linkStrength: 3.0 (locks ring geometry)
- linkDistance: 80 (tighter rings)
- centerStrength: 0.25 (moderate center pull)
- nodeSizeMultiplier: 2.0 (hub nodes visually dominant)
- Added colors: questions=yellow, comparisons=red, nav=teal

Phantom links removed from Hot Cache.md:
- Removed [[Page A]], [[Page B]], [[New Page 1]], [[Existing Page]]

New module pages:
- wiki/questions/How does the LLM Wiki pattern work.md
- wiki/comparisons/Wiki vs RAG.md
- Adds questions/ and comparisons/ domains to the graph (yellow + red nodes)

+
+**Question:** How does the LLM Wiki pattern work and why is it better than RAG?
+
+## Answer
+
+The [[LLM Wiki Pattern]] turns an LLM into a knowledge architect rather than a search engine.
+
+**Standard RAG** (Retrieval-Augmented Generation): every query searches raw documents, retrieves chunks, and assembles an answer from scratch. Nothing is built up. Ask the same question twice — it does the same work twice.
+
+**The wiki pattern** is different. When a source arrives, the LLM reads it and integrates it: updating entity pages, noting contradictions, adding cross-references. The synthesis is done once and persists. Every query benefits from all previous ingests.
+
+### The three layers
+
+1. **`.raw/`** — your source documents. Immutable. Claude reads, never modifies.
+2. **`wiki/`** — Claude-generated knowledge. Summaries, entities, concepts, synthesis.
+3. **`CLAUDE.md`** — the schema. Tells Claude how the wiki is structured and what to do.
+
+### Why it compounds
+
+See [[Compounding Knowledge]] for the full argument. The short version: each new source doesn't just add one page — it enriches 8-15 existing pages. The connections between pages are where the value lives, not the raw content itself.
+
+### The hot cache shortcut
+
+[[Hot Cache]] (wiki/hot.md) is a ~500-word summary of recent context. New sessions read it first. Cross-project references read it first. It prevents re-reading the whole wiki just to answer "where were we?"
